I have already posted a detailed guide in the discussion forum: https://cs2bus.com/app/582160/discussions/1/3409804177173076515/#c3154202142458019967

I am making this guide to let it be seen by more people, because I think ACP is a very fun functionality. There are always settings you can change that make your playthrough more interesting for you.

> Firstly, launch your game to the main menu, follow the on-screen instructions to duplicate a savegame with ACP enabled. Load into that save, make sure you now have control over your character (Bayek).

> Then minimise the game, navigate to your PC's "Documents" folder, there should be a file in that folder called "ACP.ini". Cannot find ACP.ini? See the next section.

> Open the file with windows Notepad, make sure your game is still running in the background. You can now edit all ACP settings in that .ini file.

> Save the changes you made to the .ini file, go back to your game and all your ACP changes should have taken effect.

You do not need to open or edit the .ini file everytime you launch the game. You just need to do it once and after that everytime you load into the ACP savefile your changes will still be in-effect.

FIrstly, the Steam version ACP.ini file should be in your "Documents" folder directly, not the "Documents" > "Assassin's Creed Origins" folder, make sure you are checking the correct folder!

Secondly, make sure you have created an animus hacked savegame and have loaded into that savefile at least once before checking the .ini file.

If you still cannot find the file, I have posted the content of the file here. You can simply create a new Notepad file and rename it to ACP.ini.

Alternatively, PM me and I will send you mine. Please also leave a comment here so I understand the purpose of your friend invite. Thank you.

> xxx levelscale = 0. Changes how much that faction scales relative to your character. Can be a value between -50 to 50.(not sure) For example: PtolemaicLevelScale = 50 means all pharaoh soldiers will always be 50 levels higher than you.

> PlayerBowQuiverSizeInfinite = false and PlayerToolPouchSizeInfinite = false. Can be true or false. If set to "true", you will have infinite arrows and/or tools.

> PlayerMovementSpeedMultiplier = 100. Changes how fast your character moves on foot. Max value is 1000 (not sure)

> MaxAmountOfTamedAnimals = 1. Changes how many animals you can tame at once (requires the correct skills unlocked). Max value is 5.

> WorldMapUnfogged = false. If set to "true", the whole map will be unfogged. Once that happens, you cannot revert the change (not sure)

> XY relations = 0. Changes the relationship between faction X and faction Y. For example: "RomansRebelsRelations = 0" changes the relationship between roman soldiers and rebels. Can be a value between 0 and 3. 0 is default relationship. 1-3 can be allies, neutral and hostile, though I forgot which is which.

> StressLevelDecrementationSpeedModifier = 100 changes how fast enemies give up searching you. Max value is 1000 (not sure)

> ConflictRangeMultiplier = 100 changes how far enemies can see you. Not sure what the max value is.

> InvestigationRangeMultiplier = 100 changes how far enemies search range is. Not sure what the max value is

> CivilianAndCatsDesynchRuleDisabled = true changes your desync rule. If set to "true", you will desync after killing 3 civilians or cats. If "false", you can become a mass murderer.

> PlayableCharacterIndex = 20. Changes your playable character. Can be a value between 0 and 20, though you need to figure out which is which. List of controllable characters: (potential spoiler?)

> PerpetualAdrenalineEnabled = false. If "true", you have infinite adrenaline

> DeadlyAssassinationEnabled = false. If "true", you assassinations are guaranteed to be lethal.

> PlayerExperienceGainingMultiplier = 100 changes how fast you can gain XP. Max value is 100, meaning this setting can only reduce your XP gain.

All other settings are either not commonly requested or are very intuitive. Good luck.
